The process of knocking a the dominant "Doer" over while intercourse. This happens when the "Doer", man or woman with strap-on, is having intercourse doggy style with a large individual, man in rear or woman in either. The "Doer" thrusts towards the "Taker". The ripple of the force then travels to the takers head and back to the "Doers" thrusting region. The force knocks the "Doer" over and on their back.
George Bush was suprised by the ripple factor when he pounded Rosie O'Donnell doggy style.
